 Available
Reporting and alerting

The ability to report on data-transfer progress and statistics:

  • File and object transfer statistics

 Available

Database migration

Category Product capabilities
Migration approach

  • Homogeneous – Source and target engine are the same

  • Heterogeneous – Source and target engine are different

  • The ability to convert source database engine metadata to be compatible with the target database engine

  • The ability of the tool to migrate large database objects, such as LOB and binary data types

  • Homogeneous

  • Support for LOB data types, including BLOB, CLOB, NCLOB, and BFILE
Source engine

The ability to migrate specific database engines, such as IBM Db2 LUW, MariaDB, Microsoft SQL Server, MySQL, Oracle, PostgreSQL, or others

  • MariaDB

  • Microsoft SQL Server

  • Milvus

  • MongoDB

  • MySQL

  • Oracle

  • PostgreSQL
Migration type

  • Full load only – Perform a one-time migration from source to target

  • Full load with CDC – Perform full load with change data capture (CDC) to continue replication from source to target

  • CDC only – Don't perform a one-time migration, but continue to replicate data changes from the source to the target

  • Offline – Migrate large data sets by using offline methods or external storage devices

  • Full load with CDC

  • Offline
Data transform

The ability to transform data during the migration

  • Metadata

  • Table data
Migration scope

The ability to migrate metadata and application data:

  • Metadata – Migrate database schema structure, including table, view, and stored procedure definition

  • Table data – Migrate table data

  • Metadata

  • Table data
Tool architecture, high availability

The ability support one or more of the following high availability (HA) configurations:

  • Built-in HA configuration

  • Manual HA configuration

 Built-in HA configuration
Tool sizing

The ability to size itself for the migration load:

  • Intelligent sizing during discovery

  • Manual sizing based on source database parameters, such as database size or change log

  • Intelligent sizing

  • Manual sizing
Data-type support

The ability to migrate standard and custom data types

  • Standard

  • Custom
Pre-migration assessment

The ability to assess and warn of potential migration issues before starting the migration task

 Available
Data validation

The ability to compare the data at the source and the target immediately after it performs a full data load

 Available for all tables
Monitoring and logging

The ability to log and monitor the migration task and monitor tool performance

  • Task logging

  • Task monitoring and alerts

  • Performance monitoring
Security

The ability to retain data encryption (if any) from source to target

 Available
Data selection

The ability to migrate a subset of data

 Available
Migration parallelism

The ability to migrate multiple subsets of data in parallel

Available. Multiple degrees of parallelism can be achieved when taking an RMAN backup.

After the backup is restored, the subsequent data transfer through Oracle DataGuard happens serially in the order that the transactions were executed. The transfer is done this way so that the database at the destination always remains consistent and readable.
